Hardness Increaser

4kg

Fi-Clor Hardness Increaser raises the calcium hardness level in swimming pool water. Calcium hardness is the amount of dissolved calcium (and magnesium) in pool water. If there is insufficient dissolved calcium, the water will try and take it from the grouting and concrete in the pool. High levels are not a major cause for concern provided the pH and alkalinity are within recommended parameters, but the reading should be kept below 1,000mg/l (ppm) if possible.

  • Corrects low calcium hardness
  • No need to pre-dissolve
  • ideal if your pool has corrosion problems

DO NOT MIX WITH OTHER PRODUCTS.
DO NOT DISSOLVE BEFORE USE.




Instructions

  1. Take a calcium hardness reading using a test kit or test strips. You will need to raise the calcium hardness if the reading is below 175mg/l (ppm) for liner pools, and below 250mg/l (ppm) for tiled pools.
  2. With the filtration system running, sprinkle the product directly into the water around the perimeter of the pool. Do not pre-dissolve as this could generate excessive heat. Only use when bathing has ceased and avoid areas near the skimmers.
  3. Re-test after 24 hours. If the calcium hardness level is still below 175mg/l (ppm) for liner pools or 250mg/l (ppm) for tiled pools, repeat the dose.




Warning
: Do not use together with other products. May release dangerous gases (chlorine).

Precautions: Never mix chemicals, except by dosing into the pool separately and at different times. Never add chemicals to the water when bathers are in the pool. Store in a cool, dry, well ventilated, secure place away from oxidising and reducing agents, eg, petrol, oil, solvents and organic materials; ammonia, fertiliser and nitrogen compounds; strong acids and alkalis. Avoid direct contact with pool chemicals. Should there be skin contact with chemicals, wash thoroughly.

Disposal When empty and providing it has been rinsed out on the pool. this container may be disposed of via household recycling.
